Stock market API
The stock market API built for history
One endpoint, every exchange we cover, every listing: daily OHLCV back to the first session and one minute bars from the day capture began. Register for a key and the first call is a minute away.
The archive, in numbers
Every figure is what the collectors have stored, not a projection. Bars obey the same plan history window as order-book depth.
1 min
finest grain. every coarser frame rolls up from it
Daily
back to first listing. full history for every symbol
REST + MCP
delivery. cursor paged, every series cut at the same instant
MCP
for agents. one server, every symbol
A stock market API returns price and volume data for listed securities over HTTP so software can use it directly. DataCedar's is built around history rather than quotes: GET /v3/stocks/{symbol}/bars returns open, high, low, close and volume at 1Min, 5Min, 15Min, 1Hour or 1Day, raw or adjusted, with a start, an end and a cursor. The same schema serves every exchange, so a symbol in Mumbai is called the way one in New York is.

Stock market API
What you get
What you get on the first call
A JSON array of bars, newest first, each with its timestamp, open, high, low, close, volume, the timeframe and the adjustment applied, plus a pagination block with a cursor. A daily history is one call at limit 50,000. Symbol lookup and the full master (17,000 US listings today) are two more endpoints under the same key.
Priced for the work, not the seat
Explorer is free with a registration and serves one year of daily bars and a week of minutes, enough to integrate and validate. Quant at $29 a month serves daily history back to listing and thirty days of minutes; Research at $99 ninety days; Desk at $249 the full minute archive on an isolated lane. No per symbol fees, no per call metering inside the plan's rate.
Why history is the hard part
Quotes are a commodity; a clean, adjusted, gap free series across exchanges is not. Splits and dividends are applied consistently, session calendars are the venue's own, and the minute series is the base every coarser frame is rolled up from, so an hourly bar always reconciles with the sixty minutes inside it.
Every exchange in one schema
Exchange calendars, half days, currencies and local symbol conventions are absorbed once, so a symbol in Mumbai, São Paulo or Tokyo is called exactly the way one in New York is: the exchange in the path, the same fields in the answer. A multi market study needs no reconciliation layer of its own.
Where minute history starts, and why
Minute bars begin on the day capture started for a symbol and grow by one session every trading day. For most exchanges nobody holds minute history, so it cannot be reconstructed later; the archive deepens rather than backfills. Daily history has no such limit and runs back to first listing. Every symbol page states both dates.
What this data is, and what it is not
These are source attributed bars for research, screening and backtesting, not a consolidated exchange feed. For best execution reporting or regulatory record keeping use the exchange's licensed feed. One minute is the finest resolution, and every coarser frame is rolled up from it, so a daily bar and the minute bars inside it always agree.
